The Key to Fitness is Discipline! > ATP- Adenosine Triphosphate

14 Sep 2007

    The energy source- Adenosine Triphosphate (ATP) is the most immediate source of chemical energy for muscular activity. If you suddenly jumped two feet into the air from a standing start, the energy source would be ATP.

    The energy available from ATP is very limited. If you ran 100 meters as fast as you could, you'd exhaust all of your ATP.

    The usefulness of the ATP system lies in the rapid availability of energy -- rather than quantity. Only about 30 seconds of ATP is stored in the body.

    ATP is stored in most cells, but, particularly in muscle cells. It is the most important anaerobic fuel source available. In fact, other forms of chemical energy, available from foods, must be transformed into ATP before they can be used by the muscle cells. ATP is the only source of fuel or energy the body accepts. Therefore, it is important to understand that all remaining fuel systems are simply re synthesizing and rebuilding ATP. There are two ways the body restores energy to ATP without the presence of oxygen.
